Moreover, for a given noise power spectral density ( PSD ), spread-spectrum systems require the same amount of energy per bit before spreading as narrowband systems and therefore the same amount of power if the bitrate before spreading is the same, but since the signal power is spread over a large bandwidth, the signal PSD is much lower — often significantly lower than the noise PSD — so that the adversary may be unable to determine whether the signal exists at all.

Version 6. 5, released at the end of 2004, added enhanced support for the Photoshop format ( PSD ).

In statistical signal processing and physics, the spectral density, power spectral density ( PSD ), or energy spectral density ( ESD ), is a positive real function of a frequency variable associated with a stationary stochastic process, or a deterministic function of time, which has dimensions of power per hertz ( Hz ), or energy per hertz.

For continued signals that describe for example stationary physical processes, it makes more sense to define a power spectral density ( PSD ), which describes how the power of a signal or time series is distributed with frequency.

One can prove that this periodogram converges to the true PSD when the averaging time interval T goes to infinity ( Brown & Hwang ) to approach the Power Spectral Density ( PSD ).
